The Kidde 260-CO is a system-connected carbon monoxide detector that wires directly to any UL 985 or UL 864 listed fire alarm or CO panel. Running on 12 or 24VDC panel power, it eliminates separate power supply runs and drops into your existing conventional zone wiring.

Built for the commercial installer

Alarm and trouble relay outputs keep things simple - Form C alarm relay on a dedicated zone pair, normally-closed trouble relay for supervision. The 85 dB Temporal-4 sounder meets NFPA 720 requirements without adding external notification appliances. UL 2075 listed, with CO sensitivity conforming to UL 2034 response thresholds.

Key features

SafeTest functional testing: NFPA 720-compliant CO verification without test gas or magnets
10-year electro-chemical sensor with automatic end-of-life signal when replacement is due
Alarm and trouble relay outputs: Form C alarm relay (150 mA/33VDC) plus supervised common trouble relay
85 dB Temporal-4 sounder built in - meets NFPA 720 notification requirements at the device
Tandem interconnect capable via optional polarity reversal module for multi-detector coordination
Retrofit-ready: optional 250-COPLT adapter plate for replacing Kidde 240-COe units without new box prep

System requirements

Requires a UL 985 or UL 864 listed control panel supplying 12 or 24VDC. Mounts on a standard 2-1/2 in. single-gang electrical box. Wiring accepts 14 to 22 AWG conductors.

Does this detector require test gas for functional testing?

No. The 260-CO includes Kidde's SafeTest feature, which verifies CO sensor function without test gas or magnets. SafeTest meets NFPA 720 functional testing requirements.

What panels does the 260-CO work with?

Any control panel listed to UL 985 (household fire warning) or UL 864 (commercial fire alarm) that provides 12 or 24VDC. Uses conventional hardwired alarm and trouble relay connections - no addressable loop required.

How do I know when the sensor needs replacement?

The 260-CO automatically signals end-of-life when the electro-chemical sensor degrades below threshold. The trouble relay activates and the sounder produces a distinct pattern. Sensor life is 10 years from date of manufacture.

Can I use this to replace an older Kidde 240-COe?

Yes. The optional 250-COPLT adapter plate covers the existing mounting footprint of the 240-COe without new box preparation. Same wiring connections.

Can multiple detectors interconnect?

Yes, via an optional polarity reversal module for tandem interconnect. When one detector alarms, connected units activate their local sounders.

Does it work outdoors?

No. Operating range is 40 to 100°F at 10 to 90% noncondensing humidity. Intended for interior installation only.
